Will I have that option to boot to the new ssd without having to go into BIOS?
Answer is NO - the bootorder you can only change in the BIOS. Either temporarily or permanently. See which Function keys give you BIOS access - it is on the first splash screen after power-on.
As far as your data on the HDD is concerned, I would first move it to an independent data partition on the HDD. Then you can easily use it from the OS on the SSD. Just right click on the top folders of Documents, Music, etc. and INCLUDE it into the respective library.
Once you are done with all of that and your OS on the SSD works correctly, you can delete the old C partition and system partition on the HDD. You should then also make an image of your SSD installation.
